Description
The Space Shuttle Main Engine (SSME) is a reusable, high performance rocket engine being developed to meet the performance, life reliability, and operational requirements of the Space Shuttle. Significant engine features include a staged combustion power cycle developing chamber pressure in excess of 3,000 psia, high area ratio nozzle expansion, throttling capability, and. a computer operated engine control system1. The SSME is currently undergoing certification testing at the National Space Technology Laboratoreis focusing on demonstrating maturity and reliability for manned flight this year. Current status regarding engine performance, system characteristics, and test results will be summarized. A comparison of the SSME development and certification programs with engines successfully used in the Saturn Program will be presented.
